Founded in 2014, the Environmental Solutions Initiative (ESI) is MIT’s institute-wide effort to mobilize the substantial scientific, engineering, policy, and design capacity of the MIT community to contribute to addressing climate change and other environmental challenges of global import. ESI pursues multidisciplinary research, education, events, and partnerships to help move society toward an environmentally and socially sustainable future. Based in Cambridge, Massachusetts on MIT’s main campus, ESI is powered by a lean staff working closely with students and faculty across the full spectrum of disciplines. Led by architecture professor John E. Fernandez, a leading scholar in the emerging field of urban metabolism, ESI is advised by students, faculty, alumni, and thought leaders from many sectors of society.
